sort-order.html

<p>In JavaScript .sort() orders the array alphabetically.</p>

<p>The solution to achieve a numeric sort is passing a comparison function to the .sort() method as a parameter.</p>

<p>Also, the .sort() method sorts the array in-place (mutates the original array),</p>

<p>so we should make a copy while sorting by using the syntax <code>[...array].sort()</code>.</p>

<p>If speed is really important, we can use a TypedArray.</p>

<p>Did you know about sorting using TypedArray such as Int32Array? 👇🏽</p>



<script>
  const numbers = [40, 100, 1, 5, 25, 10];
console.log(numbers.sort());


const numbers1 = [40, 100, 1, 5, 25, 10];
const copynumbers = new Int32Array(numbers1);


console.log(copynumbers.sort());


const numbers2 = [40, 100, 1, 5, 25, 10];
const ascSortedNumbers = [...numbers].sort((a, b) => a - b);

console.log(ascSortedNumbers);

const descSortedNumbers = [...numbers].sort((a, b) => b - a);

console.log(descSortedNumbers);


</script>
